145...150...160... 170...180. Her heart must really be hammering hard as she runs out of air... The trace is starting to change, there's an occasional...funny blip in it. Wonder what that means...190... That one had two blips in it... and again. 200... beeping real fast, almost like the Sword Dance. And three blips... and... it's going crazy. No more pattern, just jiggling up and down at random. No, there's the pattern again... and again... but the numbers are gone. And jiggling again. Beeping. She wiggled her hips, put her hands up near my shoulders, rose on her knees, bit her lips and managed to take me entirely into her without pause. She was very tight but also very lubricated. Her smooth face remained placid.Her style of rogering was steady acceleration until climax, and she brought me to a jolting and gushing conclusion in a very few minutes because she was so tight and so active and then sat back on my thighs looking pleased with herself. She glanced at the man sitting beside. I had slightly scared him. He looked up at me. What?! He asked with a smirk. I closed the door behind me, and showed him the paper I was holding. I got a 97% on my Trig test! I said finally. Holy shit Erica, thats great!!! He came around from his desk and gave me a big hug. He always smelled so good. Tim retracted from the hug and put his hands on either side my face. You know you are the smartest girl in the whole world, right? He said staring into my eyes. I couldnt have done it. I'm not one of those cock suckers that get it over with fast and move on. No. I love to suck a guys cock slowly, luxuriously, and lavish on him my full and unwavering attention---with no other motive in mind that to give him the best damned blow job he's ever had; and I'm always richly rewarded for it!You may be wondering at this point if I have a particular 'favorite' visitor to my glory hole. It's a reasonable enough question; and the answer is Yes! He's a young black k** who happens to live.
